Hammer crusher is a kind of equipment for crushing materials in the form of impact. It is suitable for crushing medium hardness materials in cement, chemical industry, electric power, metallurgy and other industrial sectors, such as limestone, slag, coke, coal and other materials in the crushing and fine crushing operation. An enterprise found that there was no clearance under the labyrinth seal when replacing the belt, and the bearing was damaged after disassembly and inspection. The bearing position of the crusher was worn out. The reasons for wear are as follows: Enterprise personnel found that the equipment only had oil injection holes in the process of use, and there was no oil discharge hole. Because the axial positioning of this equipment is prone to failure, the original interference failure will be caused by the expansion of the bearing at high temperature, and the bearing position will be worn after a long time of operation
In this case, we are using sauvy carbon nano polymer materials, to solve the problem of crusher bearing a wear the material consists of aviation grade resin, nano inorganic materials and high-performance carbon materials, such as advanced fiber materials generated by the polymerization process of a new type high-tech nano materials, the material has good mechanical performance, meet the car, milling, planing, grinding processing requirements, In addition, there is no thermal stress in the repair process, which will not affect the material and structure of the shaft itself. The site restoration is as follows:
1. Make preliminary preparations, such as disassembly of equipment;
2. Use oxygen acetylene to bake the grease on the surface of the bearing until there is no spark and the surface is dry;
3. Rough the surface of the worn part;
4. Clean the surface with absolute ethanol and air dry;
5. In accordance with the proportion of the Solet carbon nano polymer material, harmonized uniform, no color difference, the material is coated on the surface of the bearing position;
6. The material is cured and machined to size to complete the repair.
